Pet carrier is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welded, its characteristics are beautiful, lightweight, foldable, easy to store. Pet carrier appearance treatment is generally: cold galvanized, hot galvanized, spray, dip plastic, chrome plating, nickel plating and other methods. Pet cage is mainly used for family pet breeding and protection.
The application of electric welding mesh is more and more widely, the technology is gradually mature, electroplating rust prevention, plastic coated treatment, used for breeding, grille, plus the frame to make a fence, etc.
The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.
Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.
Railway is not only the main artery of national economy, but also an important means of mass transportation to protect people’s travel. It plays an important role in the process of economic and social development. Therefore, the safety issue is an important guarantee for railway transportation, one is a symbol of the railway transportation enterprise product quality, the other is also the focus of social attention. The off-road collision accident is one of the focus of public opinion on the railway industry. How to grasp the off-road safety management, eliminate the off-road collision accident from the source, maximize the protection of people’s life and property safety, and reduce the non-operational cost of railway enterprises is a key content of railway safety work in the new era. We should install protective nets on both sides of the railway, which are also barbed wire protective nets, so as to prevent accidents.
Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.
The advantage of galvanized iron wire after annealing: after annealing increases the elongation of the iron wire. Makes the product softer and increases the range of application. After electric galvanizing hot dip galvanizing. Copper electroplating is widely used and screen production. Galvanized iron wire is a soft iron wire product processed by low carbon steel wire through cold drawing, heating, constant temperature, and even heat preservation. Generally, the quality of ordinary galvanized iron wire will be relatively soft, the softness is relatively balanced, and the color is consistent. It is mainly used in construction, mining, chemical industry and so on.
Hook flower net is made of silk hook, the mesh is uniform, flat net surface, beautiful generous net width, wire diameter is thick, not easy to corrode long life, weaving succinct, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Mechanical equipment protection, highway guardrail, sports venues fence, road beautification belt protection network. After the screen is made into a box-like container, it can be used to maintain and support the seawall, hillside, road and bridge, reservoir and other civil engineering.
Traditional wire mesh is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the use of traditional wire mesh limitations gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven up the net wire once the mesh is too large net surface will become soft.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
Carbon spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and impact and vibration resistance. To ensure the strength and endurance index, especially to avoid changing the occurrence of cracks, is the key to produce spring steel wire. The inner quality and surface quality of the wire rod directly affect the function of the wire.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
